Hello everyone,

Just a quick question. I've got my 190E here with a 3L m103 and it would appear that my fuel economy is tanking. I've got around 170 miles (75% highway, 25% city) and I'm around 1/4 tank.

I've never done a tune up on this 3L motor (installed Feb 08) and I've never done one on the previous 2.6L motor (bought July 06)

What's all included?

Thanks
